A rectangle has width represented by x and length represented by 4x If the area of the rectangle is 80 find the value of x What is x?
length is 4x and width is x: 4x*x = 80 4x2 = 80 Divide both sides by 4: x2 = 20 Square root both sides: x = 4.472135955
What are the intercepts for the line -4x y 8?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. If your question is not answered, please resubmit it, spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (x^2) or x-squared.Restate the question: What are the intercepts of the line -4x + y = 8?To find the y-intercept, let x=0: -4(0)+y=8 y=8To find the x-intercept, let y=0: -4x+(0)=8 -4x=8 -4x/(-4)=8/(-4) x=-2With a little practice, and if the numbers are 'nice', you can almost do this by just looking at the equation, or you can think of (0,_),(_,0). My students call this "googly eyes"!Also note that most texts define an intercept as a number ("the y-intercept is 8"), but it is rare to consider "The y-intercept is (0,8)." to be correct.
How are solution and x-intercept and zero of a function and and root related?
solutions are the well solution to the problem. X-intercepts are wherever a graph cross the x axis, which are hte solutions when you have to find out what x is, zeros are pretty much the same thing although i think that include y-intercepts as well..... not sure. and roots are the same thing as x-intercepts. so they are all more or less the same thing
What represents the vertex and two x-intercepts of y equals x2-2x-35?
(1,-36); -5 and 7y = x2-2x-35; f(x) = ax2+bx+cvertex, method 1:There is a formula for the vertex, if you can remember it. (h,k) = [-b/2a, f(-b/2a)].-b/2a = 2/2x1 = 2/2 = 1. f(1) = 12-2x1-35 =1-2-35 = -36. The vertex is (1,-36).vertex, method 2:Otherwise you complete the square to convert to the vertex form, y = a(x-h)2 + k. Complete the square for x2-2x: the constant term will be (-2/2)2 = (-1)2 = 1.y = (x2-2x+1)-1-35 = (x-1)2 -36 ==> The vertex is (h,k) = (1,-36).x-intercepts, method 1:To find the x-intercepts, let y=0: 0 = x2-2x-35 (x-7)(x+5) = 0 x-7=0 or x+5=0 x=7 or x=-5. The intercepts are -5 and 7.x-intercepts, method 2:There is also a nice trick to find the intercepts: 36 = 62. the intercepts are 1+/- 6 = 7 and -5.
Can get the y and x intercepts for 4x 5y - 20?
If you mean: 4x+5y=-20 then the y intercept is (0, -4) and x intercept is (-5, 0)
What is the x- and y-intercepts of the line 4x-y equals 20?

How do you find x-intercepts?
When you're solving for the x intercept, y=0. For example, if you have a question like 3y-4x=12, and you want to find the x intercept, you substitute 0 for y. Like this: 3y-4x=12 3(0)-4x=12 -4x=12 -4x/-4=12/-4 x=-3 The x intercept is -3
What are the intercepts of 4x - 6y - 5z 60?
To find the intercepts of the equation 4x - 6y - 5z = 60, we set each variable to zero one at a time. When x = 0 and y = 0, we get -5z = 60, so the z-intercept is z = -12. When x = 0 and z = 0, we get -6y = 60, so the y-intercept is y = -10. When y = 0 and z = 0, we get 4x = 60, so the x-intercept is x = 15.
What are the intercepts for the line -4x plus y equals 8?
-4x + y = 8At the x-intercept, 'y' is zero.-4x = 8-x = 2x = -2At the y-intercept, 'x' is zero.y = 8
What are the intercepts of y 4x and minus 2?
The x intercept is 0.5 and the y intercept is -2.
Find the value of x: 2(4x + 4) = (4x - 12)?
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
9x-6 equals 4x plus 20 find x?
x=5.2
What is 4x over 20?
4x/20 = x/5
How do you find the intercepts of 4y-12 equals 4x?
To find the y-intercept you substitute in 0 for x and solve. To find the x- intercept you substitute in 0 for y and solve. If you do it correctly you should find the x-intercept to be -3 and the y-intercept to be 3.
